RAFFAELE CARBONARI, OF SAN FRANCISCO, CALIFORNIA.

ACCORDION.

SPECIFICATION forming part of Letters Patent No. 760,730, dated May 24, 1904. A

Application filed July 16, 1903. Serial No. 165,894. (No model.)

To (tZZ whom it may concern:

Be it known that I, RAEFAELE CARBONARI, residing at 1&06t Dupont street, in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Accordions; and I do hereby declare the following to be a full, clear, and

sounding of fixed concordant tones it is my present purpose to provide simple, compact, and durable means for varying at will the combination of other concordant tones, and thereby produce the pleasing chords of the common, major, and anomalous variety.

Other objects and advantages of my invention will appear to those familiar with this class of musical instruments as the following specification is gone over, in conjunction with the accompanying drawings, in which Figure 1 is a top view of the interior mechanism of the accordion, the top cover having been removed and the duplicated parts, as well as the ordinarily-constructed reed-valves, being omitted for sake of simplicity in the drawings. Fig. 2is a perspective view of the mechanism immediately connected to one of the finger-pistons, the parts being shown in their relative positions to receive the normal action of the piston. Fig. 3 is a side elevation of the parts after having been shifted to produce the combining of other concordant tones. Fig. i is a similar view showing still another shifted position to produce still another chord. Fig. 5 is a perspective view of a complete accordion made in accordance with and embodying my invention. Fig. 6 is a cross-section taken through the boxing A and a portion of the accordion. Fig. 7 is a detail View showing the connection between the fingers and the reed-valves.

Referring now to the above views by numeral and letter, A represents the box forming the body of the accordion, in which the principal operative mechanism of my invention is housed, the bellows and other features being omitted, as they are of ordinary construction. Mounted on suitable bearings 1 within this box A are the rods 2 and 3, which bear the parallel elongated cranks i and 5, respectively. Protruding through the box A is the. series of pistons or keys B, which terminate in the stems C, the latter being mounted for reciprocating movement. These stems C are provided with approximately central pins 6, which engage the upwardly-projecting fingers 7, the latter projecting from the oscillating rods 8, which are connected to the valves E in the usual manner. Evidently action of the stem C will operate these reedvalves.

B B are valves arranged upon the face of the box A, as seen clearly in Fig. 5, by means of which the volume of the sound or tones may be regulated.

Arranged in alinement with pins a, b, and 0, which are positioned near the back extremity of stem C, are the vertical fingers d, e, and j, which are pivoted at their lower ends to the rods 01, e, and f, these rods being connected to certain rods d", c, and f, respectively. The central portion of finger c is connected to the swinging end of crank 5 by means of the rod e",:while the fingers f and d are connected to the upper and lower ends, respectively, of crank 4 by means of the rods f and 0Z. Now it will be readily seen that as the lever 3 is forced downward in the direction of the arrow in Fig. 2 until it assumes the position shown in Fig. 3 the finger 0 will approach pin 6, as shown in Fig. 3. Now as the piston Bis forced inward the Valves connected with both fingers d and 6 will be operated simultaneously and the desired chord produced. On the other hand, as thecrank 4 is brought into the position shown in Fig. i the finger f will engage with pin 0 and the fingers (Z and c thrown away and free from pins a and b and another chord sounded. I

As each piston is connected in a similar manner to produce other combinations of tones, the musical possibilities of the instrument are apparent.

The construction of the principal parts of my invention being thus made known, the objects and advantages of the same will, it is thought, be readily understood.

1 am aware that various changes in the form, number, and proportion of parts of the de vices herein shown and described as an embodiment of my invention can be made without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations as fairly fall within the spirit of my invention.

\/V hat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination in an accordion, of a se' ries of pistons or keys, a series of lingers, a series of reed-valves, connections between said lingers and reedvalves, and means for bringing said fingers into or out of engagement with said pistons, whereby various tones are simultaneously sounded when a single key is oper ated.

2. The combination in an accordion, of a series of pistons or keys, a series of lingers, a series of reed-valves, connections between said fingers and reed-valves, and means for bringing predetermined combinations of said lingers into or out of engagement with said pistons, whereby various combinations of tones are simultaneously sounded as the keys are operated.

3. In an accordion or other similar instrument, the combination of a series of pistons or keys, a series of lingers, a series of reed-valves,

pivoted connections between said lingers and reed-valves, a plurality of shifting members, and connections between said members and one or more of said lingers, whereby action of said members brings said lingers into or out of engagement with said pistons, for the purpose set forth.

a. In an accordion or other similar instrument, the combination of a series of pistons provided with reciprocating stems, a series of projections on said stems, a series of lingers in alinelnent with said projections, a series of reed-valves, pivoted connections between said fingers and reed-valves, fulcrums on said lingers, and means for shifting said fulcrums to bring said lingers into or out of engagement with said projections for the purpose set forth.

In a device of this character, the combination of the body, a bellows connected with the body, an operating mechanism mounted in the body at one end of the bellows and cow sisting of a series of pistons, a series of lingers, aseries of reed-valves, connections between said lingers and the reed-valves, and

means for bringing the said fingers into or out of engagement with said pistons whereby various tones are simultaneously sounded.

In testimony whereofl allix my signature in presence of two witnesses.
